IMPROVEMENT IVN REVERSIBLE LATCHES.

Specification forming part of Letters Patent No. 124,960, dnted March 26, 1872.

To all whom tmay concern.'

Be it knownf that I, ALBERTv D. JUDD, of

l New Haven, in the county of New Haven and the same, illustrating the manner of reversing.

This invention relates to an improvement in that class of reversiblelatches commonly called stove-door latches--that' is to say, a latch in which the bolt is drawn by a thumb-lever; and the invention consists in the combination of the latch-bolt and a lever and connectingrod to connect the said lever to the said bolt, the said connection being pivoted to the said lever between the fulcruni and the other end, the said i'ulcruni being nearly in a line parallel to the path of the pivot which connects the rod to the tail of the bolt.

Avis the oase; B, the face-plate; C, the latchbolt head; D, the tail of the latch-bolt, resting in the case between the two studs or guides a a., with a spring arranged to bear against the bolt-head, the tendency of which is to force the bolt outward. On the tail of the bolt an arm, E, is arranged, froni which 'a connectingrod, F, extends to a lever, G H, the said lever pivoted at b. Through the case a screw, d, is passed to secure the case together, and this screw passes forward of and in such'relative position to the arln E or other projectionon the tail of the bolt that, when'inserted, as in Fig. 2, it will prevent the bolthead from being thrown forward through the face-plate only to the extent required for use but when the said screw is removed, then the belt will be thrown forward outside the face-plate, as seen in Fig. 3, in which position (being attached to the head E so as to turn freely therein) the bolt-head may be reversed, or set for a right or left-hand door. v

The thumblever ot' the latch-handle passes through the door below the arm H of the lever, so that when the thumb-lever is raised it raises thelever Gr H, as denoted in broken lines, Fig. 2, drawingin' the bolt, as also denoted in broken lines.

I claim as my invention- 'Ihe combination of the latch-bolt G D and the lever G H and the connecting-rod F, when the said connection F is pivoted to the lever between the fulcrum and the other end of the lever, the said fulcrurn in a line nearly parallel to the path traversed by the. pivot which connects'the rod to the tail of the bolt, substantially in the manner and for the purpose
